Nitrate Leaching to Subsurface Drains as Affected by Drain Spacing and Changes in Crop Production System E. Kladivko,* J. Frankenberger, D. Jaynes, D. Meek, B. Jenkinson, and N. Fausey ABSTRACT concerns about the hypoxic zone in the Gulf of MexicoCited by: nitrate that is vulnerable to leaching loss.
Place: Nitrogen needs to remain in the root zone to be use-ful as a nutrient. Nitrogen added through fertigation also needs careful management to avoid losses through deep percolation or surface runoff.
Concentration vs. Load. Often, leaching is not a significant factor in heavy clay soils. Other factors that can affect nitrate leaching include amount of rainfall, amount of water use by plants and how much nitrate is present in the soil system.
Impact on water quality. Nitrate leaching can have a direct impact on water quality. Cover crops in the upper midwestern United States: Simulated effect on nitrate leaching with artificial drainage. R.W. Malone, Nitrate leaching to subsurface drains as affected by drain spacing and changes in crop production system.
Nitrate Leaching Nitrate leaching is a naturally occurring process, it occurs when nitrate leaves the soil in drainage water.
Nitrate is soluble and mobile. It is no problem when it is within the root-zone, but once it gets into the ground water and other fresh water bodies it is an environmental pollutant.
Nitrate (NO 3 −) leaching and water contamination is a major environmental issue around the globe. In grazed grassland, most of the nitrate leaching occurs under the animal urine patch areas because of high nitrogen (N) loading rates.
The aim of this study was to determine NO 3 – -N leaching losses and pasture responses as affected by different animal urine-N loading rates and application Cited by: To evaluate the process of nitrate accumulation and leaching in surface and ground water, we conducted simulated rainfall experiments.
The experiments were performed in areas of m2 with bare slopes of 3° that were treated with two nitrogen fertilizer inputs, high ( g/m2 NH4NO3) and control (no fertilizer), and subjected to 2 hours of rainfall, with.
A review of methods for nitrate leaching measurement in some l y simeters an artificial. tension is applied at the bottom (Hoyningen-Hühne and Bramm, ), but this tension rarely.
The leaching amount and the leaching loss rate of NO 3-N in intensive cropped farmland are significantly higher than that of conventional planting areas. It shows that excessive fertilization increases the leaching risk of soil nitrate nitrogen and poses a potential threat to ecological environment in intensive grape by: Nitrate leaching [Butler, Charles L] on *FREE* shipping on qualifying offers.
Nitrate leachingAuthor: Charles L Butler. Everglades and Biscayne National Parks is very vulnerable to nitrate leaching Nitrate leaching as affected by artificial drains book its high permeability. Based on predictive and actual values, nitrate leaching was most affected by water table elevation, groundwater flow direction (movement of nitrates from source pollution to affecting areas farther away), and precipitation (see above table.

The Nitrate Leaching Index (LI) is an indicator of thepotential for nitrate to reach groundwater. Nitrate, because it is water soluble, moves downward as water percolates through the soil. The extent of percolation depends on permeability, pore-size distribution, soil depth to aCited by: 7. The effect of variation in seasonal temperature and precipitation on soil water nitrate (NO 3 N) concentration and leaching from winter and spring cereals cropping systems was investigated over three consecutive four-year crop rotation cycles from to in an organic farming crop rotation experiment in Denmark.

Kladivko, Agronomy Dept., Purdue University Introduction Subsurface tile drainage is a common water management practice in much of Indiana and the Midwest.
Although subsurface drainage has many benefits, it also may increase nitrate-N losses through the rootzone and out to surface waters. USDA Natural Resources Conservation Service Soil Quality Indicators ndicator C Test F Function W Soil Nitrate Nitrate (NO 3-) is a form of inorganic nitrogen (N) naturally occurring in soils.
Sources of soil NO 3-include decomposing plant residues and animal manure/compost, chemical fertilizers, exudates from living plants, rainfall, and lightning. Nitrate leaching and soil nitrate content as affected by irrigation uniformity in a carrot field.

Nitrate leaching was determined using ion-exchange resin bags at 1-m depth sampled three times during each by: • As SA matured after first year, nitrate leaching was minimized, regardless of N rate • Zoysia more prone to increased leaching as applied N increased – Greater disease at higher N rates – Lack of healthy turf cover, especially early in season • Highest tendency for increased leaching occurred inFile Size: 1MB.
The amount of nitrate leaching from the soil varies around the country, as a result of different land uses, climates, and soils. We classified Geographic pattern of agricultural nitrate leaching as a case study. Key findings. Inthe areas with the highest rates of agricultural nitrate leaching per hectare were in the Waikato and Taranaki.
The major accomplishment from these milestones is quantification of the effectiveness of cover crops in reducing nitrate leaching to tile drains and the potential of reducing nitrate leaching by using denitrification barriers adjacent to the tiles.
Anticipated effectiveness of these two practices is a % reduction in nitrate leaching. Nitrate (NO3 −) leaching from agriculturalproduction systems is blamed for the rising concentrations ofNO3 − in ground- and surface-waters around the paper reviews the evidence of NO3 − leachinglosses from various land use systems, including cut grassland, grazed pastures,arable cropping, mixed cropping with pasture leys, organic farming,horticultural systems, and forest Cited by: Impacts Pesticide leaching into tile drains was found to be a relatively small concern in non-sandy soils of the Cornbelt, compared to the potential for pesticides to run off in surface water.
Nitrate leaching into tile drains requires more research and critical analysis of alternative ways to treat drain effluents. Strategies to decrease nitrate leaching in the Brimstone Farm Experiment, Oxfordshire, UK, the effect of straw incorporation L.
Chemical and biological characteristics of alkaline saline soils from the former Lake Texcoco as affected by artificial drainage. G., Harris, G. L., Howse, K. R., Mirza, N. and Pepper, T. J Cited by: Understanding N leaching from fertilized agricul- vestigation of N trace-gas emissions, soil N cycling, N ture is important for several reasons.
First, the largest leaching losses, crop yield and grain quality, and the components of N leachate, nitrate (NO) and nitrite economic impacts of File Size: KB. We provide a statistical analysis of determinants of groundwater nitrate levels.
We assess the capacity of the Gross Nitrogen Balance to predict nitrate levels. High average temperature and precipitation decrease groundwater nitrate levels.
The Gross Nitrogen Balance is a stat. significant predictor for nitrate levels. Its capacity can be improved if precipitation is taken into by: Risk of High Nitrogen Leaching in East and South Central Nebraska J Nitrogen will leach when soil water content becomes greater than the maximum soil water holding capacity, as excess water will drain below the root zone carrying within it soluble nitrogen, mostly as nitrate.
A national map of nitrate leaching (kg N/ha/yr) was produced from input maps of land use and stocking rates. The model was developed by running Overseer® for all soil and climate combinations in New Zealand (LENZ level II) – see Figure 1.
The results are expressed as. AGR - Nitrate Leaching Potential, Irrigated (WA) This interpretation is designed to evaluate the potential for nitrate-nitrogen to be transmitted through the soil profile below the root zone by percolating water under irrigated conditions.
Leaching is a natural environment concern when it contributes to groundwater contamination. As water from rain, flooding, or other sources seeps into the ground, it can dissolve chemicals and carry them into the underground water supply. Of particular concern are hazardous waste dumps and landfills, and, in agriculture, excess fertilizer.
Leaching of soluble elements from cultivated soils is a major concern to meet the target of agricultural sustainability in most areas. The effect of biochar application to a cultivated soil on water drainage and the consequent solute losses was assessed during a trial carried out over two consecutive growing seasons.
Biochar was added to a loam-texture soil, at 0, 1, and 2% d.w. : Angela Libutti, Anna Rita Bernadette Cammerino, Matteo Francavilla, Massimo Monteleone. Brian Krienke, Nebraska Extension educator, discusses the risk of nitrate leaching and talks about nitrogen applications during the growing season.
Protecting water resources from nitrate-nitrogen (NO 3 -N) contamination is an important public health concern and a major national environmental issue in China. Loss of NO 3 -N in soils due to leaching is not only one of the most important problems in agriculture farming, but is also the main factor causing nitrogen pollution in aquatic by: Soil Texture Effect on Nitrate Leaching in Soil Percolates By T.
Powell Gaines and S.T. Gaines The results showed that soil texture affected the retention of NO 3-N in the sand, which adsorbed the least amount of NO 3-N at ppm, followed by the Greensmix at ppm, Nitrate-Nitrogen Concentrations.

Journal of Environmental Quality Abstract - Surface Water Quality Nitrate Loss in Subsurface Drainage as Affected by Nitrogen Fertilizer Rate and NO 3 leaching need to be quantified to develop soil and crop management practices that are economically and environmentally sustainable.
Minimizing Nitrate Leaching from Cropland. Is nitrate leaching a problem in Montana. Nitrate is a form of nitrogen (N) that is plant-available. It can come from fertilizer or decomposition of organic matter and manure, and is highly soluble and easily lost to leaching as it moves with water below the root Size: KB.
REVIEW AND INTERPRETATION. Nitrogen Management Strategies to Reduce Nitrate Leaching in Tile-Drained Midwestern Soils. Dana L. Dinnes,* Douglas L. Karlen, Dan B. The first is too much nitrate getting into our groundwater aquifers that are used for drinking water supplies.
High concentrations of nitrate in drinking water that’s used for making infant formula poses a risk to young infants because they can’t process that nitrate that we as adults can. Regional governing organisations in New Zealand are developing new policies to assess and manage the effects of land use intensification on water quality.
Such policies require an assessment to be made of potential nitrogen leaching losses from different land uses, particularly where land use may be becoming more intensive.
